When light energy is absorbed it can turn to heat, trigger a chemical process or cause other changes. If you are implying that we can somehow "extract" a color from light, I'm afraid it can't be done.Light has no inherent color. Color is only a result of our eyes interacting with various wavelengths of light. Once the light is absorbed, all information about the photon that was absorbed is lost.

Yes. It's called a prism. A diffraction grating would work too. Neither of those uses any energy (aside from the light itself) for their functioning.
I don't know what industrial uses there are for coloured light that would require it to come from the Sun, however.
